Do you have any questions?

The testo 350 is a rugged, easy-to-use exhaust gas analyzer designed to meet the highest demands when it comes to carrying out precise industrial emission measurements and providing proper data administration. The Analysis Box can be operated with up to 6 gas sensors, 5 of which are optional. This allows you to select freely from sensors for CO, NO, NO2, SO2, H2S, CxHy and CO2.

Increased measurement range for unlimited measurements even when gas concentrations are higher

Easy-to-change gas sensors and easy access to wearing parts

Sealed housing with built-in impact protection for use in harsh conditions

Emission checks in industry: Professional technology meets practical design. The testo 340 combustion analyzer is an easy-to-use flue gas analyzer that can be fitted with up to four different gas sensors.

Can measure CO, COlow, NO, NOlow, NO2 or SO2

Extended measuring range for use in environments with high gas concentrations

The testo 350 is a rugged, easy-to-use exhaust gas analyzer designed to meet the highest demands when it comes to carrying out precise industrial emission measurements and providing proper data administration. The Control Unit complements the testo 350 Analysis Box (separate product) and makes it easier to control emission measurements.

For diesel engines, the smoke count is an important parameter, not only for evaluating emissions, but also for the correct adjustment of the fuel injection. With the smoke tester testo 338, the determination of degree of blackening is revolutionarily easy; no stationary measurement equipment, no analysis electronics – with just one portable one-hand measuring instrument.

Handy and robust: easily possible to carry to the desired application site

Determination of soot concentration (mg/m3) as well as Filter Smoke Number (FSN) or Bosch number

A heated sampling system is necessary when the situation requires maximum measuring accuracy, for instance (e.g. if there are high concentrations of NO2 or SO2 in the flue gas). For circumstances such as these, we offer our heated industrial probe set.

A high degree of measuring accuracy, even if the flue gas contains high concentrations of NO2 or SO2

Measurements in applications with flue gas temperatures of up to 600 °C

Short time needed to set up the heated industrial probe (ready for operation in 20 minutes maximum)

The flue gas probe from Testo makes it possible to carry out efficient flue gas measurements on industrial engines. In the case of diesel engines, the permanently welded-on preliminary filter provides protection from diesel particulates. It can be used at flue gas temperatures of up to 1,000 °C
